Actually there were two ways I thought about doing this.
First fork stellar and make the coin anonymous.Stellar is already deemed a sharia compliant blockchain by the Bank of Bahrain and maybe change the algo

Secondly have a token based on gold or silver price as the old arabic community traded and a coin like this would pass the banks Sharia test.I was looking for some people to kick around both ideas to see what was best.If it was metal based it can easily be seen that all coins have the metal backing by storing it at a metal seller who will show account balance

Sharia Compliant Stable Coin Based On An Ounce Of Silver

According to Thomson-Reuters, the global Islamic economy is projected to reach upwards of 3 trillion USD by 2021. Within this market, cryptocurrencies will play a role in the ever-emerging capitalization of global markets and trade. In this light, it is important to understand the issue of cryptocurrencies and their compliance with Sharia law. The Bank of London and the Middle East (BLME), a Sharia-compliant bank, states that “the main principles of Islamic Finance are the avoidance of all haram (harmful) activities such as charging interest. In addition to the prohibition on charging interest, Islamic financial institutions must ensure that ambiguity (gharar) or gambling/speculation (maysair) is minimized in transactions and contracts.” In order to be compliant, cryptocurrencies must meet these standards, as well as additional crypto regulations.
